Google has purchased the cutting-edge robotics firm which supplies mobile research robots for the Pentagon. The tech giant is keeping secret what it will produce with the acquired technology.

Boston Dynamics, an engineering company that designs robots like BigDog, Cheetah, WildCat, and Atlas, is now the eighth robotic company to join Google’s ranks in the last six months, the company confirmed Friday, according to The New York Times.

The robotics company – based in Waltham, Massachusetts – is known for its fascinating robots that have a sense of balance and can walk and run on almost any kind of terrain. Boston Dynamics was established in 1992 and is known for supplying robotics technology mostly for Pentagon clients, including the Defense Advanced Research Projects Agency (DARPA).

Google has so far refused to reveal what it is planning to do with the new technology, but the internet giant’s robotic efforts, headed by Andy Rubin, will certainly have impressive capability due to the new acquisition. The company also said it will keep the financial aspect of the deal confidential.

The tech giant said that it intends to honor the existing military contracts the firm has, but does not plan to become a military contractor.

As of now, Boston Dynamics has a $10.8 million contract with DARPA to supply several humanoid Atlasrobots. The machines are set to participate in the DARPA Robotics Challenge, which awards the winning maker with a $2 million prize. The contest evaluates robots’ ability to function during natural disasters and catastrophes such as an earthquake or a nuclear power meltdown.

“Competitions like the DARPA Robotics Challenge stretch participants to try to solve problems that matter and we hope to learn from the teams’ insights around disaster relief,” Rubin, the man behind the development of the Android mobile operating system, said in a statement released by Google.
